SharePoint 2013 preview install office web app preview cannot auto install requirement software

Hi Nehach,

SharePoint 2013 preview install office web app preview cannot auto install requirement software

If the following software is not install on sever, I hope to auto install before I install 2013 office web app preview. How to use stsadm or powershell javascript to know the soft is whether existing on the server.

NET4.5、PowerShell 3.0、KB2592525

Thanks,

Tom
